One such singl INTRODUCTION TO SUPERZAP. BY THOMAS.  J.  KEENE.(The following article was originally published in the Inland Empire ADAM Users Group (IEAUG) newsletter.  This version is the result of laborious transcription by David Sands, to whom we express our sincere appreciation.  In order for us to accommodate the graphical representations, of the screens displayed by Superzap it was necessary for the article to be printed in full page format.  Let me know if you prefer this layout to our regular double cmplexity with ED.COM or the dozen or more variations of ED.COM.  Another CP/M transient command of substantial complexity is DDT.COM.  It combines assembler and disassembler functions and is generally viewed askance by most CP/M users.However, even powerful word processors such as VDE, Word Perfect and WordStar may not provide all of the editing features needed to create the kind of text files we require.  I have been writing about the problems encountered in extending our ADAM to take advantage ofstly for our own pragmatic reasons.  It was a means to an end and of little or no concern as a procedure.  The active pursuit, of an ideal technique is of academic interest only, and probably futile as well, because "best" is contingent upon our definition of the term.  Who is to say what the relative merits of various program features are? So, it is with some trepidation, that I propose yet another way to edit files. There are many devoted ADAMites who maintain that FILEMANAGER is the best Utilit------ An article in "High Lights" by D.

It is probably the fastest copying utility extant but that is all it does!Word processors are basically file editors.  ADAM CP/M 2.2 comes with a collection of transient commands, one of which is is a word processor of sorts.  That is the ED.COM file.  It has been vilified far and wide for being so extremely difficult to use.  I share that view myself.  I have been told that Irv Hoff used ED.COM as a word processor.  It is true that you could edit files of great coolumn format.  BDC.) Often, there is a better way to do something, than the way we have been doing.  And, just about as often, we are reluctant to change.  Although different is not necessarily better, there is something to be said for expanding one's horizons with a little variety.  I can remember, in the early days of the ADAM, there were many of us intimidated by CP/M.  The manual that came with our CP/M 2.2 was awesome!  Ultimately, most of us bit the bullet, and came to terms with CP/M, but mo the capabilities of modern dot matrix printers.  As I have pointed out, there are printer codes that just can't be incorporated into our text, for a variety of reasons.  I have discussed the use of DU-V87.COM as a companion tool to VDE to achieve that objective.I have long been aware of a great file editor named ZAP and the upgrade, SUPERZAP.  I tried ZAP several years ago but I discarded it as being too awkward.  I found that other programs like DU-V87 were much more user friendly!  My good frieninaccessible because of a CRC error or other corrupted control information.  This is because SUPERZAP will read and write sectors to and from the disc, using BIOS functions directly, thus bypassing the BDOS safeguards and restrictions.  In this way, you can modify the contents of sectors, that will cause normal CP/M disc operations to fail because of a BDOS error condition.One of the things I DON'T like about SUPERZAP is the unconventional commands used to perform very prosaic functions.  For insttill not user friendly and there are a few strange quirks in the use of the file.  But once you become familiar with it, it does have some advantages.  For example it has a search function which permits you to search for an ASCII string (up to 20 characters long) or a sequence of hexadecimal bytes.  For that matter, so does DU-V87.  But SUPERZAP searches much faster than DU-V87.  Another advantage it has is that it can search for a string by file (instead of by sector as DU-V87 does) or it can searc confusing but it interferes with the functioning of the program.  If you don't remove these two lines, you will not be able to access the entire sctor when you are in the edit mode.  Another manifestation of this malfunction is in the location of the string you are searching for.  It will always point to a location directly beneath the location of the string you searched for.  In a search for a word, the program displays a small arrow that points to the start of the word.  If you haven't removed thf a grave accent character, this can be done by simply repeating the search by hitting one keyboard key.  Even if the blocks containing the file are not contiguous, it proceeds directly to the next block in its search, no matter where that block may be.  This is a major advantage of SUPERZAP.  Incidentally, the ADAM version of SUPERZAP is called ZAPADAM.There is another outstanding feature of SUPERZAP, which no other disassembler I know of has.  And that is, you can often repair a program that is d George Havach often praised the virtues of SUPERZAP but in its orginal form is was far from ADAM friendly.  George configured it for the ADAM and posted it on the Compuserve and Genie boards.  It was accessed only a few times and so the program is almost unknown among ADAM users.  I have found that the ADAM version of SUPERZAP works quite well and is a worthy candidate for everyone's file collection.The documentation ranks among the poorest I ever recall reading.  To begin with, the program is sance, the arrow keys are not implemented and to move the cursor down you must hit Control-C (^C).  To move the cursor up you use Control-F (^F) and to move the cursor left you use Control-E (^E) and to move the cursor right, you use Control-D (^D).There is another VERY IMPORTANT admonition I should make that is most significant.  As soon as you load SUPERZAP, you should hit Shift-UNDO.  If not you will be plagued with two lines of meaningless garbage at the bottom of your screen.  This is not onlyh every file on the drive.This ability to search for an ASCII string by file is very similar to the FIND.COM file by Irv Hoff, except that in SUPERZAP this is a built-in feature of a disassembler which permits you to search for a string (ASCII or Hexadecimal) and then immediately go about modifying the file.  One terrific advantage this has, over the block search of DU-V87, occurs when your file is scattered all over the disc as frequently happens in CP/M.  If you are searching for each occurence oose two lines with Shift-UNDO, the arrow will be on the wrong line.  Much worse, if you change th contents, it will appear that you are doing it correctly, but in fact it will make the change in the line above it.  It looks OK, but believe me, it wont't be.  It is easy to avoid this problem by use of the Shift-UNDO maneuver.When you are in the edit mode, your screen presentation of the sector is virtually identical to the screen pesentation of DU-V87, with one nice improvement.  At the top of the dry List - B:  ????????.???>CPSVO614.91A    >CREDIT.BAK      >CREDIT.TXT SD.COM>WORDPRC3.BAK    >WORDPRCE3.TXT   >NEWFILE.BAK NEWFILE.BASThis display of files is the directory of the B:Drive.  The cursor will appear in the upper left corner.  The legend that appears at the top of the screen is very useful.  The characters (such as ^D, ^F, TAB, Z) appear as control characters--that is they are in inverse video.  This makes them rather hard to see, but if you have your system configured as I recommendecimal search, the arrow will be in the digital section of the sector display.  But even better than that, you may toggle the arrow from one area to the other.  Suppose you had requested an ASCII search for a grave accent, which happens to be located at byte 69.  The arrow will point to the grave accent character in the ASCII section of the data.  If you toggle it to the digital section (with the tab key) the arrow moves over to byte number 69 in the digital area and will be pointing to 60 (which itor modes.  You can enter and exit the Edit mode from either the Directory or the Sector mode, but once in the Edit mode, you can only leave it by returning to the mode from which you entered it.  That is, if you entered the Edit mode from the Sector mode, you can't go directly to the Directory mode.  You must first return to the Sector mode and then go to the Directory mode.The commands vary in the different modes, for example the B command in the Sector mode is used to find a designated block, bu basic command.  If you start the program with: A>ZAP B:  <CR>You will be operating on the B:Drive is what is called the Directory mode.  The screen will appear something like this: SuperZap 5.1D Cursor left    N Next directory page      D Change Drive^E Cursor right  P Previous directory page  S Select track/Sector^F Cursor up     M Set directory Mask       E Edit file^C Cursor down   U Change User Number       T Type fileTAB Next file     (current: 0)              Z Exit from SuperZapDirectoigital data, there is a row of numbers that identify the bytes in a line.  This makes it easy to know which byte is being edited.  However the find function of SUPERZAP minimizes this advantage because it points an arrow to the target rather than telling you its location.Like DU-V87, you can search for a character or string by ASCII text or by hexadecimal notation.  If you request an ASCII search, the arrow will point to the string in the ASCII section of sector information.  If you request a hexaded in a previous article on the use of VDE, these will appear as black characters surrounded by a bright yellow background all on a deep blue screen, which makes them highly visible.There are three operating modes of SUPERZAP; the Directory mode, the Sector mode and the Edit mode.  Actually the authors of SUPERZAP refer to the Edit mode as a "sub-mode".  Each of these modes has a different screen presentation and each provides a special function.  You may move freely between the Directory and Secs the hexadecimal code for the grave accent).These are some of the salient features of SUPERZAP.  Now let's consider how to make use of this fine program.  I suggest that you rename the program from ZAPADAM.COM to ZAP.COM.  It is 2K larger than DU-V87.COM (which is 8K) and can be located on an editing utility disk with other appropriate files.  To execute "ZAP" you may type ZAP and a carriage return.  This will bring you to the basic screen of ZAP; you may also invoke a couple of variations of thet in the Edit mode it means to go to the bottom of a files.  When in the "Typing mode" (not actually a "mode") the B command means to page backward.  But there is one command about which there is no ambiguity.  That is the Z command.  This always means to exit SUPERZAP back to CP/M.SUPERZAP uses terms that are unique.  At least some that I haven't encountered in any other program.  And the documentation blithely uses the terms with a minimum of clarification.  There is a term called a "mask." In thint you can readily move to any drive and then either, select a file or select the sector mode.   A UNIQUE USE FOR VDE266 There are times when you are plowing through a DOC file, trying to find a discussion of some term or other, and you go nearly blind trying to locate the term.  Such might be the case in trying to locate each description of the term "mask" in the rather awkward documentary on SUPERZAP.  VDE266 can make this chore a breeze.  The doc file for SUPERZAP is named ZAP51.DOC.  Just opceal all files other than "BAK" files from access.  Similarly, there are a couple of CREDIT.??? files that can be chosen for access.  Also a couple of WORDPRC3 files.  This directory "masking" operation can also be invoked in the command line that executes SUPERZAP.  I noted above that there were several ways to initiate the SUPERZAP program.  Two have already been mentioned (ZAP <CR> and ZAP B:  <CR>).  You can also designate a specific file to be edited on the command line.  The filename may be amimplest place to start a discussion of the use of ZAP would be with the Directory mode.  This is the mode that you would most likely use to enter the program and it probably the simplest to use.  Earlier in this article is the screen presentation when using the ZAP B:  command.  In the left column at the top of the screen are the cursor control commands I don't care too much for this, so I used my QUIKKEYS program to make a macro key assignment to my arrow keys.  I assigned Control-D (^D) to my leftlso use the command line to execute in the Sector mode.  This command line will start the operation in the Sector mode on the B:Drive: A>ZAP B:DSK:  <CR>That colon after DSK is important!  If you omit it, it will think you are searching for a file named DSK and you will enter the directory mode with a diagnostic that the file was not not found.  None of these command enhancements are necessary, because the simple ZAP command will put you into the directory mode on the default drive, from which poe context it is used here, it means to hide files from access other than the ones you are specifically interested in.  You can be in the Directory mode and mask certain files from being displayed (and accessed) or conversely, you can use a mask to make only certain files accessible.  If you want only "COM" files to be accessible, you can use a mask to make only certain files accessible.  In the directory above there are several files that have a filetype of "BAK." A mask can be invoked that will conen ZAP51.DOC with VDE and when it is loaded use the find command Control- Q F (^QF) to search for the word "mask".  The beauty of this is that you can view every occurence of the word and you can read it in its exact context, as it appeared in the documentation.This is fast, easy and sure beats a random visual search for some reference or other.  And you will not miss or skip over any oblique application of the tern which could easily be missed in a visual search. USING THE DIRECTORY MODE The sbiguous or specific.  A command line that will open a specific file on the B:Drive named CREDIT.BAK is as follows: A>ZAP B:CREDIT.BAK <CR>A command line that will mask our all files from access except BAK files (that is, an ambiguous filename) would appear thusly: A>ZAP B:*.BAK <CR>I haven't found this masking technique particulary useful.  If you just select the ZAP B:  command you will enter the Directory mode in which all of the files on the B:Drive may be accessed quite readily.You may a arrow key; Control-E (^E) to my right arrow key; Control-F (^F) to my up arrow key and Control-C (^C) to my down arrow key.  In this way I use the arrow keys in their normal function.  The last command in the left column is the TAB key.When your cursor has been moved down to the files in the directory list, you can move it to point to the next file in the list.  Whenver you want to perform some operation on a specific file, you move the cursor to that file and then select the operation listed at trectory List" you will see the file name of the file you just entered in the directory mask operation> If you had typed in TEST.TXT then this would now appear in the directory list postiion of the normal directory mode screen.  All of the other files that appeared before will be missing.Suppose that you had entered a fictitious filename and tried to edit the file, you would get a diagnostic comment that the file was not found.  While in the alternate mask mode, there are a couple of other commands.ile I want to work on.So if you have a large number of files on your B:Drive, they won't all appear on the first screen, so you will have to hit N to bring up the next directory page of filenames.  Similarly if you are on the second page of the directory, you must hit P to go back to the first page.  The third option in the second column is "M Set directory mask".  I discussed the mask term above.  If you select the M option (just hit M; no carriage return needed) then you will see this screen: SDELETE key.  SUPERZAP is easy to use but it is also very limited in the things it can do.  One serious shortcoming is the failure to provide for printing a hard copy of your work.  DU-V87, on the other hand.  will print out all of its operations.  To me a hard copy is essential.  So if that is what I need, I'll just have to use DU-V87. and tried to edit the file, you would get a diagnostic comment that the file was not found.  While in the alternate mask mode, there are a couple of other commands.will move down to the first question mark in the file type.  If you have entered your file type and hit a carriage return (or if you hit a carriage return with the cursor at the first question mark in file type--that is, you want a filename but no file type) then you will be immediately returned to the screen mask that was displayed before you hit M.  This is the normal screen of the directory mode.  A change will have occurred in this screen.  Instead of the ambiguous question marks in the line "Dihe top of the screen.  The TAB key moves the cursor one file at a time.  But it is just as easy to use the arrow keys.  If the cursor is pointing to the file CPSVO614.91A and you hit the right arrow key the cursor will jump to CREDIT.BAK.  If you hit the down arrow key, it will jump to WORDPRC3.BAK.  Similarly, the left arrow key jumps, to the filename to the left (not a character at a time, but a filename at a time).  So I find the TAB key to be less convenient than the arrow keys in locating the f  The ESC command refers to the escape key and it will return you to the normal directory mode screen immediately.  The TAB key toggles you from the file name line to the file type line, back and foth with each tab key operation.  The DEL command is not often used in normal ADAM CP/M.  There is no DEL key on our keyboard as in some computers.  You can get the DEL function with a Control-DELETE if you feel it necessary .  Or you can suse the QUIKKEYS program to put the Control-DELETE function on the uperZap 5.1^D Cursor left ^V Insert on/off TAB Toggle name/type^E Cursor right DEL Delete character ESC Use Current MaskFile name ==>????????? <=File type ==> ??? <=The cursor will be found under the first question mark in File name (as shown).  The use of ^D, ^E and ^V are self explanatory.  You may type in a filename at the location of the question marks (indicating ambiguous characters).  If your filename is less than the allotted eight characters, just hit a carriage return, and the cursor SUPERZAP Continued:                                  EDITING A FILE In the directory mode, you may select a  file for editing by placing the cursor at the appropriate filename and then hitting E. As an example, let's select the file WORDPRC3.TXT  for editing.

You can see how this is a safety feature.  You may edit your data  from either the directory mode or from the sector mode.  If  you  prefer  to  edit your file by sector (the way DU-V87 does) then you should chose the sector  mode.  This  works  very  well.  But if you want to edit by file, then choose  the directory mode. It is this directory mode of editing by file that gives SUPERZAP  one of its strongest appeals.

The heading is different but the data presentation is quite similar.

This is the first screen of the directory mode.  If  we immediately select S, we will go to the sector mode and will enter this mode with the first block of the directory. This will be Group zero, (or Track D of  the  B:  Drive).  The  new screen will appear something like thisde by hitting S in the directory  mode  and  L  in the sector mode. Note  the  Z  command  which  will  return  you  to CP/M. When you are ready to explore  the  editing  features  of  SUPERZAP,  hit E and you will get the next screen. You may then try your hand at editing.                               SuperZap 5.1^D Cursor left              CR New line ^E Cursor right             TAB Toggle hex/ASCII ^F Cursor up                ^W Write changes to disk ^D  Cursor down             ^Q Quit and ca changes. If there are to be multiple changes in this sector, you  can  withhold  the  Control-W  command  until  all changes have been completed. If you have  finished your editing in this sector, either the Control-W or  the  Control-Q  will return you to the previous screen (Sector Mode).Now suppose you would like to make a digital  area  edit. An easy example would be to change the  byte  "32"  to  "33".  What this will really do is change the ASCII entry WORDPRC2 to WORDPRC3.

But I have a reason for suggesting a digital area edit.I want to demonstrate the use of the H  command  (Find  hex  sequence).  At the Select option (where  your  cursor  will  be) enter H and a carriage return. It will prompt you with "Find" and you  enter  the  number  "32"  and  a  carriage return.

The TAB command is one of the very useful features of SUPERZAP.  As  soon  as  you  begin to edit this sector, your cursor will be  placed  in  the digital area at the first byte (as shown). You may move this around the digital  area with the cursor controls. If you  move  the  cursor  to  the  extreme  position  in  the  data  area it will recirculate back to the other end.

This is one of  the few utilities that permit you to even view a sector with a CRC error, much less repair it. It is not a procedure for the faint hearted.

When you press a Smart key (the black keys), a command is typed on the screen which is then executed by pressing RETURN.  The commands include   things like:  DIR (for Directory of files on disk /tape), or DEL (to delete a file), etc.  The Smart Keys just type the   name of frequently used commands on the screen which would perform things like  FORMAT, SAVE, PRINT, QUIT, TOP, BOTTOM (of page or           document).  And when you do QUIT, the original Smart Key     settings appear at the bottom of the screen; or,3) Execute your favorite modem program (+ dial the number,   using MEX) and have a new set of Smart keys with commands    for your modem operation like:  YOUR NAME, PASSWORD,         DOWNLOAD, SAVE, UPLOAD, EXIT.  And after you saved the       messages from the BBS to a file and exit from the modem on the screen, you can also have them automatically  execute that command without you having to press the return  key? It's easy!  When you tell TDOS what Command you want a  Smart Key to print on the screen, put a ^M immediately       following the command name.  For instance, if you frequently use a program called MAINT12.COM (by Guy Cousineau), type in MAINT12^M when answering the above question for Smart Key I. Thereafter, when using TDOS, to execute the fantastic        utility program called MAINT12, bet you can invent ways to use the Smart Key        setting programs beyond my above uses.If you are a MOAUG member and want to try out the new Smart  Key Setting programs yourself, send me a formatted blank     tape or disk, and sufficient postage for me to mail it back  to you in the same package, and I will send you these neat   programs, including ".DOC" files explaining how to operate   them.  In fact, if you include a note that tells me about    the drives and expander (if any) you are using (like:M TO SAY OR DO.  And it includes the ability to execute another command to reset those Smart  Keys to the original settings.  But, what can this do for Me???Imagine this:  By pressing a single Smart Key, you could:1) Boot up the TDOS installation file, have all the          questions answered for you and have the TDOS system written  on a new Tape or disk; or,2) Boot up the wordprocessor called VDE266.COM and           automatically have a whole new set of Smart Keys available   at the bottom of the screen f or you as a time saver.   TDOS, however, gives you the ability to decide what command name the Smart Keys will print on the screen, and will       execute the command for you, as follows:When you originally set up TDOS on your Tape or Disk, one of the many questions you are asked is:  do you want to "change the Smart Keys?" If you type in Y, for yes, you are then     prompted to rename each of the Smart Keys.  But did you know that in addition to having the Smart Keys type the name of a command      program, the file you saved is called up in the VDE266       program automatically, complete with new Smart Key settings  to enable you to automatically go to any message containing  your name (FIND your name), NEXT PAGE, PREV PAGE, TOP FILE,  BOTTOM (of file) and SAVE.  When you exit VDE266, the        original smart key settings are reset and the file is sent   to a tape or disk after being "crunched" (all blank spaces   removed in text) for archive purposes, and the screen        cleared.And I'll just hit Smart Key I, and it types the command name on the screen and (in effect) presses the return key for you.  The above feature, plus the ability of TDOS to automatically perform a whole series of commands and tasks through the use of ".SUB" (short for SUBMIT) files, sets the stage for the   introduction of a fantastic new series of programs from Guy  Cousineau.  THESE NEW PROGRAMS ALLOW YOU TO EXECUTE A SINGLE COMMAND, WHILE USING TDOS, THAT CHANGES YOUR SMART KEYS TO   ALMOST ANYTHING YOU WANT THE  one   160K disk drive, two tape drives and a 64K expander).

Every second pixel will draw, but only on every other row; the results are QUARTER tone insasically quit working completely until the unit is cleaned.  The Colecovision/ADAM holds up great compared to newer equipment.  I guess they just don't make them like they used to.To clean the ColecoVision/ADAM cartridges you could go out and buy a Nintendo Cleaning kit for $9.99 at the local toy store.  The kit comes with three cartridge cleaning pads with nice handles, a large system unit cleaning pad, and a bottle of cleaning solution.  The cartridge cleaning pads have a slight bend on the handle that  Apr 93 15:34> Barry Wilson wrote: BW> I need to know abut shippaing adam BW> disks drives to a chap who purchased BW> some from me. BW> On one type you are supposed to put a BW> disk in when you ship (I THINK BW> doubler sided to keep the heads frofj BW> hiting) and the only you ship empty.The older drives need some padding (like a blank disk) to  keep    the heads from banging around.  This applies to single  and double sided drives.  The newer drives have a lock that holds the heads in place wat are giving you trouble.  Another method is to use a cotton swab with a little isopropyl alcohol and rub it across the cartridge contacts a few times.  The cleaning solution especially made for cleaning cartridges is made by 3M and smells a lot like tape/diskette head cleaning fluids, which consist of isopropyl alcohol.  So you should be ok in using isopropyl alcohol without fear of ruining a cartridge, plus you are only going to clean it once anyway and may never have to again.  As far as cleaning the dule"?   But you just played the game last week and it worked fine!  Normally all you have to do is shut the unit off and take out the cartridge and put back in.  Reseating it may have given better contact.  If it still does not work, don't panic just yet, the problem may be some dirt or oxidation on the game cartridge or system unit.  I have noticed a big market in cleaning products for Nintendo cartridges and system units.  It is common for these units to get dirty in a very short period of time and b‚CÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÞÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿTo:  Barry Wilson               Message #:  14From:  Guy Cousineau              Submitted:  09 Apr 93 09:15:00   Subject:  Shipping disk drive           Status:  Public Received:  Yes                            Group:  Adam (1)In a message to All <05makes getting into the cartridge area a breeze.  All you need to do is add a couple of drops of solution and run the pad up and down on the cartridge contacts a few times and you're all done.  The system cleaning pad will not fit into the ADAM game cartridge port without some cutting to it's plastic case.  I have not cut mine up yet to see how it fits yet because my unit works fine.   Most people, however, will not likely need to get a cleaning kit.  Plus they are a bit pricey just to clean a game or two thhen the door is open.  Putting a  disk   in those actually decreases the protection.  The trick  is to      check and see if you can close the drive door with no  disk in it.  If the door won't close then you're fine.  If it will close then put a disk in it and close the door.Of course, you could go halway in between and ALWAYS put a  disk   in but NEVER close the door.  That method will ALWAYS  give you    added protection when shipping a disk drive.Apologies for the long reply but I hope that the expp:  Adam (1)In a message to All <16 Apr 93 13:51> Peter Ames wrote: PA> Well I have been using these two pokes PA> on and off with SmartBASIC V1.0 PA> If you would like to park your hard drive while in basic PA> the most simple way is to just type from the promp... PA> poke 64885,152now that is a novel approach...I'll have to remember that  one! PA> This will park the hard drive just as if you had press the PA> shift escape key....

Of these, I know of and have used no less  than four such processes. Recently I have seen ads for software for the IBM PC's that make   big claims for the advantages of compressing files.  One such       software program sells for nearly $200.  I visited a local          software store to inquire about the program and, as it was          explained to me, it did virtually nothing in addition to the        compression programs in the CP/M public domain. I have commented in earlier articlee. The AT&T system proposes using fiber optics telephone lines  (many are already in operation).  But this system is competitive  only    with the existing cable companies.  It is unlikely that AT&T  would allow cities to franchise competing TV distribution systems.  They have been completely successful in blocking local    telephone competition and there is a lot more at stake here.   Both Hughes and AT&T are planning on compression techniques to  enable   them to offer vastly greater programming than ihe bandwidth of conventional television,   with no percep- tible loss in quality.  These new techniques are    being pursued with great vigor by AT&T and Hughes Communications.   The latter company is investing hundreds of millions of dollars  in a speculation involving an entirely new form of direct  satellite   broadcasting of pay-per-view programming.  The crux of  the new     system involves Hughes new high power satellite and the  com-       pression techniques developed in the computer world.  They  auppliers of programs to fill those   600 channels.  And these deals are proceeding at a feverish pace. What are the main advantages, if any, to compressing programs      used by the ADAM? For anyone who now has a hard drive, the answer   is obvious.  Nearly everyone I have talked to, who has a hard       drive, has already run out of room and can add new programs only    by deleting an existing program.  10 Meg drives are saturated in    the first week of operation; 20 Meg drives may take a month or  so. re than two of the     superstations (WTBS, WGN or WOR).  With the Hughes system, you  can have it all and the local Public Utility Commission would  have no  jurisdiction over the operation.  The huge power of the  Hughes     satellite would make it possible to have superb reception  with a   receiving dish no larger than an LP record.  Of course,  the        customer would need a complicated decoder to decompress the         desired signals and to decipher any special anti-piracy encoding    they might uss about the many advantages  of CP/M for ADAM users, and one I have made particular note of is  the compression capabilities that exist in CP/M.  There are no          programs that I am aware of, that operate under EOS which even      come close to providing for text compression. Cable television is completely agog over a new technique that      will permit elec- tronic compression of video images so that        vastly greater amounts of data can be transmitted within the        restrictions imposed by ts possible  with     current cable delivery systems.  The AT&T system is almost          exclusively a metropolitan operation.  Rural areas cannot be        served the way that the direct satellite systems can.  On the       other hand, they are not faced with the immediate possibility of    competition.  Anyone with the capital can put up another  satellite to compete with Hughes.  There are many aspects to these schemes and at the present time, the crux is not technical.   The bottom line is developing sre     talking about transmitting 600 channels directly to the  consumer.  No cable connections!  No deals with city councils over right-of-way franchises!  This new concept removes one of  the most objectionable aspects of current cable franchises, ---no       competition!.  If you live in a city that has approved a par-       ticular cable company, then you, the consumer, are at their mercy   as to quality, cost and program availability.  In California, it    is a given that no cable company may carry mo But even conventional discs soon become so filled with  material   that most of us have literally hundreds of discs dedicated to storing material.  And often this storage is  archival in nature.  We don't use it very often, but when we want  some of   this archival stuff, we want to be able to retrieve it.   I know    that I have a record of every time I have ever been on  CompuServe  or Genie or any other bulletin board.  99% of these records are just dead storage, but I wouldn't want to scrap these   fe was the "SQUEEZE" process, it  was   possible to unsqueeze the files as they were extracted from  the    library file.  Later, when the preferred compression program  was   the early "CRUNCH" technique, it was necessary to extract the       component files and then "un- crunch" them one by one.  Before      long a delibrarying system evolved which would uncrunch the files   as they were being extracted.  Unfortunately, the improved CRUNCH   programs that appeared were largely incompatible with the earlierhalf or even less  if the files are compressed first.  Now this is truly a dollars  and   sense reason for becoming proficient in compression techniques. Most of you are familiar with the process of librarying or         archiving files.  Here, too, there are several procedures           available to us ADAM users that enable us to collect and com-       press files into one single file for ease of transmission and       storage.  The advantages are myriad.  If you have a program like    MEX or VDE, it ierick compression procedure (still based on the Lempel-Zev    techniques) appeared in Japan and soon migrated to America.  This   program (commonly called the LZHUF pro- cedure) was totally void    of documentation and was very touchy.  It's main claim to fame  was that it provided a somewhat deeper degree of compression.   This    improvement was more than offset by the confusion that  resulted    from it's use.  For one thing, there was no built-in identifi- cation of a compressed file that told the userrams. In order to cram as many programs as possible into a library       file, it is customary to compress the member files.  Most  programs that create library files require that the com- pression  be        accomplished separately before collecting them into a library       file.  However, in removing files from a library, it is normal      practice to decompress (or not, as you prefer) the compressed       files as they are separated out of the library, Even way back  when the only compression techniquiles.  So the storage just grows and grows.  A few years ago I     consolidated my CompuServe transactions onto a special set of       discs dedicated to just these files.  And the first thing I did     was to compress every one of these files.  This alone reduced the   storage to less than half that of the uncompressed files. Still not persuaded? Well one real money saver is in the           transmission of programs over long distance lines with a modem.     Your communication charges cane be reduced to    crunch procedures.  That is, a file that had been crunched with a   late version of CRUNCH.COM, could not be decompressed with an       earlier version of UNCRUNCH.COM.  This caused no end of problems.   However, in time the early versions of CRUNCH were completely       displaced with the newer and more effective versions.   Ultimately, the degree of compression was no longer being improved with the upgraded versions of CRUNCH.  However, the        incompatibility picture still did not improve. A mavs highly desirable to have all of the per- tinent   ancillary files collected together in one group.  In VDE you may    want to collect the usable COM file with a documentary file and a   pristine unconfigured COM file as well as the install program and   its documentary file.  Often a library will consist of 15 or more   related programs.  The kinds of programs that profit from this      librarying technique are many.  For example the BRADFORD set of     files can easily exceed 30 separate but related prog how the    file was compressed.  In the early days of squeezing, the           algorithm renamed the filetype (file extension) so that one could   tell at a glance that a file was squeezed.  It automatically        changed the middle character of the file extension to "Q".  Thus    CONNECT.TXT was renamed to CONNECT.TQT.  The same was true of the   CRUNCH programs.  They always renamed the file to put a "Z" in  the middle character of the file ex- tension.  CONNECT.TXT would  be    renamed to CONNECT.TZT. lable for CP/M.  This process will permit    you to collect files into an ARC file (like CONNECT.ARC) and at     the time of collection the files may be compressed.  What           compression technique was used? Why, the most popular one around,   naturally ---CRUNCH28!  The big difference in the naming of         archived files was that CP/M files used the file extension of       "ARC" while IBM files used "ARK".  But there remains a problem      with compatibility.  Many, many files that were archived unt.  They claimed that they were somehow re- sponsible   for the introduction of LZHUF to America and as such, they were     entitled to call the shots.  Such, of course was not the case.      But it was over a year before this situation was resolved (sort     of). So now we have SQUEEZE, numerous versions of CRUNCH and LZHUF  all are being used simultaneously.  Old timers are still posting  files on bulletin boards that use the SQUEEZE procedure.  A few  find     LZHUF compelling, though the vast majorityexists in a television        picture.  For many many years, it was a given that a TV scene       required enormous bandwidth in order to provide decent  resolution.  In fact serious compromises were made in the early days of NTSC standards in the trade off of resolution for           bandwidth.  Everyone knew that clusters of data appeared at every   harmonic of the scanning frequency and that in between these        harmonics was a vast wasteland of bandwidth that contained no  data whatever.  But compre tangent using a procedure       known as ARCING.  This was slang for archiving.  An ARCED file  was no more nor less than a library file that was incompatible  with    everything else in sight.  This of course is known as the  IBM      syndrome.  It must be incompatible, ---it is written!  So  everyone fell all over themselves to create an archive procedure  for CP/M.  This was not as easy as one might imagine, but ultimately the bugs were worked out (sort of) and an ARCING         procedure was made avai But LZHUF didn't have this feature.   Much worse than this, the system languished because there was            absolutely no agreement on what to rename the file extension,  even when the renaming had to be done manually.  Some proposals  were    forthcoming but the NIH syndrome (EG-1NFH-0ot EG-1IFH- 0nvented     EG-1HFH-0ere) prevailed.  As a matter of fact, just as  the rest of the CP/M community began to concur on a common designation, a group of ADAM community prima donnas refused to go   along with ider  IBM rules will simply not respond to UNARCING programs of CP/M.   Even  though the files themselves are completely compatible with  CP/M    (such as text files and RLE graphic files), they cannot be          accessed and extracted with CP/M unarcing programs.  This is a      truly devastating situation that continues to this day. The television compression situation is remarkably similar to  the compression of computer graphics such as RLE files.  It is          astonishing how much voided bandwidth  are using CRUNCH28.  A de- librarying program was needed which would          decompress member files no matter what means of compression was     used.  Just such a program appeared in LT28.COM.  But even that     was not quite universal.  Finally LT29.COM seemed to provide the    universal delibrarying capability that was needed.  Still other     procedures appeared.  Most offered nothing but confusion in that    they were merely different but not better procedures.   The IBM world was off on their ownssion was not in the province of               communication engineering, at least at the time the standards  were adopted.  The Hughes and AT&T systems are not bound by any          agreements that evolved in the United States or Europe.  Since      these are closed systems and compatibility is of concern to  nobody but Hughes and AT&T (the public would not have direct  access to    these transmissions), they could be as crazy or as sophisticated as the designers pleased.  Not only that, but if  the propeduring speech, it consists  of just two or three simplistic movements repeated over and over.      Smoothness is missing altogether.  Just think of the vast amount    of savings this creates.  Only a few cells are needed to provide    the animation. Even the conversion of a motion picture to a television image      calls for a 25% increase in transmission time just to achieve       acceptable aesthetics.  This results from two separately arrived    at set of standards.  In the early days of sound motion pn.  Many of you have  seen  this "WELCOME TO IEAUG" graphic.  It appears on the screen  in full color.  I captured this particular scene with the SMARTBASIC program "PS".  This full color picture was then          converted over to CP/M with ADAM.COM where I could use a            compression program on it.  The file was 15K in both the EOS        version and the CP/M version.  After I had compressed this file  it was a mere 1K in size.  That is a 15:1 reduction in storage.   I    have tried the same procees per second the increased film speed     permitted about 7500 cycles per second.  Not that this is  anything approaching high fidelity but it was "acceptable".  The  Society of Motion Picture Engineers anticipated technical advances that would ultimately permit about 10000 cycles per        second which was then regarded to be high fidelity.  Thus the 24    frames per second was adopted for all time. Television, on the other hand, had another problem to cope with.   And that is the inability to avoid pated  cartoons.  At one time the rising production costs nearly forced  the major   animation companies (like Disney) to cease making elaborate feature presentations like "101 DALMATIONS".  These       films used highly detailed scenes with smooth, life-like motions.   Contrast this with the low budget Hanna-Barbera productions.  In    these low cost cartoons, there is 99.999% stationery scenery with   an absolute minimum of motion.  Facial expressions rarely change    and if the mouth is scripted to move r deals can be made, they would abolish the present            incompatibility between the US, Great Britain, Germany and France   who all have national standards based on some very antiquated       concepts, much like 50/60 cycle 225/120 voltage power  conventions. In the ADAM world we can get a feel for the extent of the          reduction of storage requirements in the area of graphics.  I  have used a graphic that I created for one of our IEAUG promos at  the   various computer fairs we participated iictures,   the standard of 24 frames per second was agreed upon.  Silent       films had been using 16 frames per second (and home movies still    use 16 frames) and this was based on the bare minimum to avoid      flicker.  But with standard 35mm motion picture film, this low      speed of 16 frames per second was too slow to achieve even the      barest acceptable sound quality.  At 16 frames per second the       highest frequency that they could record was about 5000             cycles/sec.  With 24 framdure on a number of RLE graphics           including the well-known shuttle picture with the same results.     This is quite surprising because we are now taking a video image    and compressing it with more effectiveness than the compression  of a text file.  I guess I feel that it is surprising because of  the  high bandwidth requirements generally associated with video         images. In the compression of video movies the potential is even  greater.  This can readily be illustrated by considering animower hum from getting into  the circuitry.  In the United States, our power industry had  adopted   60 cycles/second many years ago.  So the NTSC correctly  concluded  that the picture rate had to be a multiple of 60.  And  since they  also adopted a two-field inter- laced scanning arrangement, it was decided that the field rate would be 60  fields per second which meant that the picture rate was half that  or 30   pictures per second.  This proved to be a very wise decision.  Although broadcasting facilie difference in standards was no assurance of incompatibility between German TV sets and American signals.        These standards were never meant to accomplish incompat- ibility.   They agreed that it would be better for our troops to use the       German 25 picture frame rate to avoid the inevitable hum problem    which would manifest itself as a wild series of hor- izontal  black and white bars madly racing up the screen, virtually obliterating the picture.  Not only that, the German pirates        wat to 25 for the same reason; they were using 50 cycle power   there. Let me cite you a personal experience I had with this situation.   Back in 1956, when I was stationed with the Air Force in Germany,   an agreement had been reached by the State Department to permit     the Armed Forces to set up a low power TV station for the Armed     Forces.  The German government was most concerned for their         fledgling state-run television industry.  They wanted assurances    that our radiated power was minimalo the   old U.S.  standards.  And, as expected, when we went operational,   the video image was so cluttered with hum bars that the picture     was unwatchable.  The AFEX (Air Force [Post] Exchange) had made a   contract with RCA to deliver a huge number of TV sets for those     who needed a TV but didn't bring one over with their household      goods.  These brand new sets performed every bit as miserably as    all the rest.  So an extremely expensive modification pro- ject     was created to make these neds in the State department simply were       ignorant of the technical world, and they just had no notion of     the ingenuity of hackers.  (They still don't).  It was so easy to   make a few minor circuitry changes and VOILA, ---American TV in     German homes!  At least those living near the American Air Base. I was placed in charge of the installation of this facility  which immediately led to a close liaison with West Deutcher  Rundfunk,    the German equivalent of the FCC.  We quickly agreed that thties could be relied upon    to totally eliminate power hum in their video, the same could not   be expected for TV receiver manufacturers.  These receiving sets    had to be built to realistic cost standards, so some hum was        inevitable.  If this hum was the same rate as the video image,      there might some modulation of the video image but it would be      stationary and not wander up and down the screen so it would        generally be imperceptible.  In Europe the vertical scanning rate   was setching the American TV would also get the same diabolical bars.   So we quickly struck an agreement that our American TV station      would use the 25 cycle frame rate.  It was a done deal and we  each met with our respective State department officials, each  receiving assurances that there would be no objections. I had to return to the United States on a personal emergency and   was gone for about a month.  When I returned, I learned that        Washington had overruled our agreement and so we were back t and that American TV  standards prevail to assure complete incompatibility with German  TV          receivers.  At that time the German programming was sparse  (barely three hours a day) and not especially entertaining.  The  lure of   "I Love Lucy" and all of the anticipated U.S.  programming would surely intrude upon their own market.  In that,   the heads of state were correct.  But counting on the               incompatibility of the two nation's standards was wishful           thinking.  The best minw RCA sets functional.  However,        nothing was done about any other TV receiver.  That was up to the   individual set owner to solve.  And this created an im- mensely     lucrative business for all of the electronic technicians in the     area. Back to the 25% increase in transmission time due to the 24  frame movie standard and the 30 frame TV standard.  It is impossible to send 24 frame movies over the 30 frame TV without     some chicanery.  So this is what they do; they transmit four        framwould not go mad trying to  discern these changes.  And often the changes were obfuscated by            deliberate camouflage.  In a relatively short time we had           developed extremely effective concepts.  As a matter of record,     these studies resulted in the first electronic video recorders      ever made.  We needed to make video recordings of photographic      images so that we could process the data electronically.  We  first looked into the only electric video trans- mission processes in exio  stop and hold the fourth frame for two projections is sure one  jerky        sounding machine.  They really clatter!  So you see that,  by       sending that extra frame, we are wasting 25% of our precious        bandwidth just to accommodate this standards incompatibility.   Now you couple that with the enormous vacancy of data that  compression can deal with, you can begin to grasp the potential for cramming 600 channels into something like 1/100th the           bandwidth. And thus far, nothing has from  captured  German Magnetophone recorders that were the booty of a  Captain who had returned to CBS after the war.  Another was sponsored by Desilu productions based on Colonel Ranger's  captured magnetophones.  He headed up the Signal Corps intelligence team that was evaluating captured German               communications equipment.  Incidentally the Captain was part of     that same team.  Crosby literally wore out the motors of his        equipment and so he contacted Ampex Electric who were speciae. In 1946 I was assigned to the Photographic Laboratory (later       known as the Recon- naissance Laboratory) at Wright Field, Ohio.    At that time we were exploring the possibilities of eliminating     redundant data in photographic scenes.  The idea was that we  could superimpose two views of the same target and then note only  the    changes that had occurred between the first and second photo.       Thus, if equipment or troop movements or construction had           occurred, the photo interpreter es normally and then they hold and repeat the fourth frame  and send it again.  Oddly enough, you are not aware of this when  you   watch a movie on your TV.  But if you have a VCR, you can  watch a  rapid action scene in VCR slow motion and then you can  see that    every fourth frame is displayed twice.  If you watch a  runner, you can see four natural forward moving views and then the fourth frame is repeated.  Sounds like it should be jerky,  but it isn't.  However, the special projector that is used tstence and these were the slow telephoto machines   used in the newspaper business.  The then current American  systems were abysmal, so we contracted with Muirhead-Jarvis of  Great       Britain for the first such device ever attempted.  At the  same     time we saw a potential for magnetic recording which was  then      emerging for the lower bandwidth audio field.  There were  only     three American contenders that had any expertise in audio  magnetic recording.  One was being developed by Bing Crosby, been said about invoking the HANNA-      BARBERA effect on conventional movies.  It is completely  practical to avoid transmitting all of that repetitious non-moving scenery in about 90% of all motion picture scenes.  I have   never seen a study on just how much of an average movie scene is    totally redundant, but my guess is that it is well over 95%.  And   I am including the most minute, subtle motions that provide so      much reality, but which actually account for a minimum of the       overall scenlists   in unique motor manufacturing.  That's how Ampex got its start in   magnetic recording equipment.  The third company was Magnecord of   Chicago. We contacted them all to see if they could conceive of any         practical way to increase the bandwidth to video needs.  Ampex  was interested but had no concept of what was needed.  They  simply     didn't have any ideas.  Ranger was off on cloud nine and  was       talking to himself when we last saw him.  Magnecord was full  of    ideas, and so theyhis could vastly reduce the storage requirements for   all kinds of TV fare.  Most broadcasting stations store all of      their news footage and other special programming.  The vast         amounts of storage must be overwhelming.  I can envision other      data transmission systems using these same compression concepts.    For example, stock market data could be delayed slightly to         compress ten minutes of data into a few seconds and then time       sharing this actual data transmission with dozens by others in the Photo Laboratory, in particular a   genius by the name of Amrom Katz.  Katz was primarily a             mathematician but profoundly well versed in optics and              electronics.  There was a similar problem being studied by the      Radiation Lab at Wright field.  They were working on RADAR and      they took wanted to be able to sort out parts of targets that       differed from one scene to another.  The principle difference  here was that their respective views were only fractionorage text files to CP/M and then compress them to a reasonable   size.  It is to your advantage, be- lieve me!Thomas J.  KeeneIEAUGff of resolution for           bandwidth.  Everyone knew that clusters of data appeared at every   harmonic of the scanning frequency and that in between these        harmonics was a vast wasteland of bandwidth that contained no  data whatever.  But compretor).  In no time at all it  was possible to have Radar images that were void of clutter and  only   displayed targets that moved from one frame to the next. From this you can see the enormous potential for compressing       normal motion pic- tures into a fraction of the space normally      required.  In fact, it would be entirely feasible to record any     television production and then use these compression techniques  to cram the signal into a fraction of it's original size.  Just        imagine how t built the very first magnetic video  recorder    that we are aware of.  By early 1947 we had achieved real success with these designs.  RCA heard of our investigations   and they sent their head of recording to Wright Field to see if     they could get into the game.  They had a genius on their staff  by the name of Alex Badmaieff (a Russian) who became so enthralled at the prospect that he left RCA and formed his own      company.  In any event these developments were being watched with   great interest of other data     senders, ---other stock exchanges, commodity markets, news          gatherers.  They all would only have to wait a few seconds while  a commutation process (like time sharing on Compuserve) served  them  each in turn. It's no wonder that data compression is the greatest thing since   sliced bread! And you Adamites have a good beginning at your        fingertips.  Even you EOS holdouts!  You can learn to master some   of the rudiments of CP/M, at least enough to convert your dead      sts of a  second    apart whereas the Photo Lab shots might be days or months  apart. As it happened there was a major reorganization of the             Engineering Division at Wright Field and the RADAR work was  merged with the Photo Lab and it was inevitable that Katz would  spot a    commonality.  So the success of the Photo Lab preliminary  studies  were applied to the RADAR problem and, low and behold, an  entirely new concept was borne, known today as MTI (EG-1MFH-0oving G-1TFH-0arget EG-1IFH-0ndica‚CÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÞÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿIT WAS ONLY YESTERDAY              I was looking through some of the early IEAUG        newsletters and I found a few interesting news items I'd like to   share with you. These are from the 30 January 1985 newsletter:    Is it time to give up on you   400,000 after all the existing parts are put together. The unsold  ADAMs were apparently bought by ODD LOT, a division of REVCO.      Coleco has indicated that they will make more technical support    available to third party developers, thereby encouraging third     party production of software and peripherals.  Coleco's toll-free  hot line will continue for another year, and they will continue    to honor all warranties.2. ABOUT THIRD PARTY PRODUCERS:    A. Many companies have stated they will contsoftware in DDP and disc format until     the end of 1985 or even mid-1986. Educational and games            cartridges should be available for an indefinite period of time.   Here's some of the software  Coleco will bring to us:              1) CPM 2.2 - released 18 January in DDP format, and  soon on disc. This program will permit compatibility with WESTICO  (25 Van Zant St. Norwalk CT 06855) software to include WordStar,   MicroSoft Basic, GoldStar, CP/M Workshop, SuperCalc, Mailcom and   many others.     C. Unreal Software Company (Sage Enterprises) recently         released its PACKCOPY. This program will copy almost all DDP and   disc software, to include games. It is similar to ADAM Utility     Kit. Price is $41.50.3. ABOUT HONEYWELL:    Coleco's contract with Honeywell has another four years left,  so repairs will be no problem. Honeywell is continuing to carry a  good supply of games, software, peripherals, and supplies for the  ADAM.  Walk-in service is available in Torrance and San Diego.mmer.              4) Others include - Best of Electronic Arts, Coleco  Home Utility Pack, Math Quest, Berenstein Bears (mapping skill     game), Cabbage Patch Kids Workout (children's educational  game),  and MANY MORE text and graphic games.    B. Coleco produced only a small quantity of 64K memory         expanders and AdamCalc, so these may be hard to find. A final      production run of disc drives is in the planning. There are about  250,000 ADAMs currently sold with a total production of about   r ADAM?    Is it time to throw it away?    Sell it?    Hide it?              We don't think so, and neither will you after        reading the latest from Coleco, third party producers and          Honeywell. This information was compiled AFTER Coleco announced    that it would stop producing ADAMs, so it should be reliable.1.  ABOUT COLECO    A. Yes, Coleco has stopped producing the ADAM computer  but    not ADAM utility and educational software. Coleco states that  it  will continue to produce inue producing     for ADAM. These include -Micro 2 Alpha 1, Sunrise, Data Backup,    Victory, C&C, SoftSync, Personal Peripherals, Extended Software,   Spiral, Home Entertainer, Unreal Software, and MANY MORE.    B. Image MicroCorp has announced that they will produce a 64K  memory expander for the ADAM which will be available in February.  Also, they say they will produce a speech synthesizer and an RS-   232 interface later in the year. The RS-232 will enable            substitution of another printer.Some of these programs will require the 64K memory    expander and/or a dual drive. It will also enable programming in   Cobol, Pascal and Fortran. The price should be about $70.00.              2) SmartBasic 2.2 - An expanded version of the       current Basic which will be available on DDP and disc.              3) ADAM Utility Kit - will be available on DDP and   disc and will enable copying most software to include  SmartBasic, SmartLogo, SmartFiler, etc. Should be available during the spring or suAND DON'T FORGET !!!!    If any of you hear or discover something that the rest of the  group would be interested in, please pass it along to us. Also,    pass information about our group to ALL other ADAM owners you      meet. The more support we receive, the more we can give.4.

He has produced   a number of kits that include the circuit board, parts, and even a   time of day clock chip.

I want to have some idea about where I'm going in these articles. It's a novel idea to be sure, but seeing as how it's the beginning of a new year and all, perhaps some perspective can be sketched out.So let's see.....I have an article to write about the ADAM emulator, and more specifically about the utilities that accompany thurce code around here from both Guy Cousineau and Dale Wick explaining the secret of it.  All I have to do is read and understand. It sort of strikes me that if you're going to write ADAM software, it should at least look like ADAM software, which means use of the Smartkey display.Apart from that, what else.....Oh yes..... Dale Wick's MIC compiler could occupy some time. I wonder if there's anything useful I can learn to do with that.And Patricia Herrington gave me a disk back at ADAMCON, with a MIDI s a Windows based program that allows the user to transfer .BMP files into powerpaint format. This program comes complete with windows to view both the bit map image and the powerpaint image simultaneously on the same IBM screen.  The user can make adjustments to a couple of parameters (dithering and gamma) that can improve the powerpaint image. So sometime this year I have to correct my understanding of the word 'dithering' which probably means something completely different from what I think it means.Mehacker; (requested by two readers - that's  plenty the ADAM world). Bob Slopsema thinks I've forgotten how to write; something  should be done about that; Bart Lynch thinks I'm dead. I haven't logged onto the Assylum in ages. Preparation for ADAMCoN 10 (October 8 - 11). If I don't go I *will* be dead. PJ will see to it personally.        And on and on.......  Note that this activity is associated with four of my computers. There are another 12 to occupy my spare time. Change of Subject.I ome quite an expert, and if I can swing it, I'll excercise managerial tactics and get him to write about ADAMBOMB 2. When in doubt, delegate and disappear.There are a couple of programming problems I'd like to spend some time with.a) How to scroll text into a text window from a text file, so as to be able to read it forwards, backwards, or jump around from page to page. How to prepare and format text files so they can be read by a BASIC program.b) How to activate the ADAM Smartkey display. I've got soe ADAM emulator These are the programs that make it possible to import a disk full of programs and data files from an ADAM formatted disk, read by an IBM disk drive, saved as an image in the Emulator directory, and sufficient to  convince  the Emulator that it's looking at an real ADAM disk. There are various sizes, and there is also a method of storing this data back to an ADAM disk for use on a real ADAM.  The whole process works.Another of Marcel de Kogel's magnificent contributions to the ADAM world ifile she wants me to play and spice up for her. Haven't forgotten about that PJ, and I did load the file one night, listened to it, and determine that I can work up, probably, a pretty good sounding version of your 'blues' tune. And if I should run out of things to do, there is more.... The documents on how to build an ADAM mouse that Bob Slopsema sent many moons ago; The documents describing how to install a monitor jack on the Colecovision game unit; A return to the adventures of Backslash Byteanwhile, has anyone else tried these programs? Do you realize that your source of graphic material for ADAM Powerpaint screens is now infiniitely larger than it was?I want to learn more about SmartBASIC 1.x. It would be nice to write some useful software for ADAMCON 10. Have no idea what, or even if.  Bob Bair (now on Compuserve) is sending me some maps to make my life easier when playing ADAM Bomb 2. He knows the game inside out, and he's decided to help some of us who watched him at ADAMCON 09. He's becrecently joined the local Macintosh user group, because I now own a Mac. It's a relic, an SE, but it was enough to qualify me for membership in a group of friendly and very helpful people. Last Tuesday night, I had 25 of them in the living room. We take turns at hosting meetings. A thought occurred to during the course of that evening. It wasn't a new thought, but it still has no answer.Why are there not more IBM user groups or computer clubs? I joined one in Ottawa, but it died for lack of interest. Turnbeen said about invoking the HANNA-      BARBERA effect on conventional movies.  It is completely  practical to avoid transmitting all of that repetitious non-moving scenery in about 90% of all motion picture scenes.  I have   never seen a study on just how much of an average movie scene is    totally redundant, but my guess is that it is well over 95%.  And   I am including the most minute, subtle motions that provide so      much reality, but which actually account for a minimum of the       overall scend here locally.  The BBS sysop that was carrying the ADAM and CP/M FIDO- net echo's for me has served formal notification to his users that he'll be winding up the BBS forthwith. He has lost his E-mail feed, and paying users are on the decline.  I'm not at all surprised to hear of this decision. Tony has been a rock solid sysop for years in this valley, but now he's re-married. He and his new wife have started what promises to be a highly successful marketing business.  He simply has no time. So FIDO hereIt would take a lot of scanning though with Omni Pro (character recognition), but maybe this could lead to a complete ADAM  archive someday.  I have 25megs available to start. My site is "http://w3.one.net/~spitman:  The ADAM section is  not up yet. I just have my "Weird Video Game World" section up  so far.< Jerry > I sent him an E mail reply (spitman@one.net) and his reply to me follows.  I tried to post Steve's message to me on Dale Wicks' ADAM mailing page but it was sent back to me. If you thinf 50 messages or more a day.  Many good ideas were exchanged, help provided, arguements vented, jokes told, you name it. It was fun, and I'm sad in a way to see it all come to an end. -Ron Mitchellards incompatibility.   Now you couple that with the enormous vacancy of data that  compression can deal with, you can begin to grasp the potential for cramming 600 channels into something like 1/100th the           bandwidth. And thus far, nothing has ed out that the only reason members attended meetings was to have a shot at winning the freebies brought by various guest speakers. Here in Comox there is no IBM group. I'm told that is so because IBM owners don't really like to talk to one another. From the few short weeks I've  been in the MAC group, I've concluded that MAC owners never stop talking to one another. That's more like what I'm used to, and continue to enjoy about the ADAM world. Speaking of which... we seem to have lost part of that worlÌ1 ×73This received from Jerry Vrancks of 463 ADAM newsletter, via the e-mail trail.----------------------------------------------------------------Hi Bob, I received a snail mail note from Steve Pitman the other day and it went something like this:  Steve > I'm going to add an ADAM section to my website soon. I  need to get permission from Sol Swift to see if he will let me  reprint some N & Bits stuff.  Wouldn't it be great to create  Nibbles & Bits online and have it searchable (every issue).   will become a thing of the past, if it wasn't already.  Traffic on the ADAM FIDO echo has been non-existant for months. I'd been putting out Ron'Week through last summer and fall, but that didn't seem like a very good idea given the Internet distribution. There were only one or two ADAMites frequenting FIDO, Guy Bona and Paul Elshoff (Keystone ADAM Users,Winnipeg).   Both have Internet addresses.It all served to bring back memory of the days when FIDO traffic on the ADAM echo screamed along at the rate ok this information is worth reading maybe you can get it on Dale's page and use it on the ANN disk.  May you and your family have a great 98.
